A Delta FA once jokingly told me their motto is, "We're not happy until you're not happy!".
I think it fits here.

I personally never liked the term "gate lice". The lack of overhead space, has resulted in a mad dash to get on the plane as early as possible. I don't blame people for rushing to get onboard. Also, Delta's boarding is confusing to the inexperienced. One would think that if you are Zone 1, you are the first group to board. In reality, Zone 1 is really Zone 4.
